摘要： A conductive layer of an electrophotographic photosensitive member includes a binder material, a first metal oxide particle, and a second metal oxide particle. The first metal oxide particle is a zinc oxide particle or tin oxide particle coated with tin oxide doped with phosphorus, tungsten, niobium, tantalum, or fluorine. The second metal oxide particle is an uncoated zinc oxide particle or tin oxide particle. The content of the first metal oxide particle is not less than 20% by volume and not more than 50% by volume based on the total volume of the conductive layer. The content of the second metal oxide particle is not less than 0.1% by volume and not more than 15% by volume based on the total volume of the conductive layer, and not less than 0.5% by volume and not more than 30% by volume based on the content of the first metal oxide particle.

摘要： A surface layer of the electrophotographic photosensitive member has a change region in which a ratio of the number of carbon atoms with respect to the sum of the number of silicon atoms and the number of carbon atoms gradually increases toward a surface side of the electrophotographic photosensitive member from a photoconductive layer side, wherein the change region has an upper charge injection prohibiting portion containing a Group 13 atom, and a surface-side portion which is positioned closer to the surface side of the electrophotographic photosensitive member than the upper charge injection prohibiting portion and does not contain the Group 13 atom, and the distribution of the Group 13 atom in a boundary portion between the surface-side portion and the upper charge injection prohibiting portion is precipitous.
